Ferenc,
What a small world!
That class in Dallas was the very first teach of the excellent Oracle
Server Internals seminars anywhere, ever. Originally, Scott Gossett was
supposed to teach all of them, but he was booked at the time so Oracle

Used it for large application upgrades, works a charm, cut down the time by
about a third. But it does not work on every platform, because when I set it
and then perform a transaction, upon dumping the redo log, I find my
transaction in there. But thanks Tim.
BTW, I was in that class, you ran it
For the previous poster, my understanding of
_disable_logging is that all of the normal operations
take place EXCEPT the actual physical write. Hence
you will get log switches, check points etc etc. If

Yes, I have tried the _disable_logging, does not work on all platforms. DB
starts up fine, but redo log is generated, evidenced by log switching going
on.
Also if I do a normal DML (large-ish one to verify), then dump the redo log,
I see my transaction there, so for a 420R, running

Once I was teaching a DBA class and mentioned _DISABLE_LOGGING.
Immediately, I saw every head in the class look down, scribbling furiously!
I had to backtrack very quickly and

since I first worked with you, I've always regarded you as best amongst the best
(and I don't give that title lightly), and you have substantiated it once again.
Thanks for the info, this is great ! Can't wait to freak out some minds
